Mother substrate for display panel, method of cutting the same, and display panel prepared by the method

A display panel comprising:

• a display area comprising a plurality of pixels;
• a non-display area surrounding the display area;
• a first substrate comprising a first edge extending in a first direction and a second edge extending in a second direction which intersects with the first direction and forms a vertex with the first edge;
• a second substrate that faces the first substrate;
• a seal pattern that comprises a first seal pattern extending in the first direction, and a second seal pattern which extends in the second direction and forms a vertex with the first seal pattern, the seal pattern being located between the first substrate and the second substrate and surrounding the display area;
• and
• one or more dummy spacers disposed on the first substrate within the non-display area,
• wherein the non-display area comprises:
• a first non-display area between the first seal pattern and the first edge;
• a second non-display area between the second seal pattern and the second edge;
• a vertex area that abuts the first non-display area and the second non-display area and is adjacent to the vertex of the first substrate;
• and
• an average arrangement density of the dummy spacers in the vertex area is smaller than an average arrangement density of the dummy spacers in the non-display area or 0;
• and
• wherein:
• the dummy spacers comprise a first dummy spacer located in the first non-display area and a second dummy spacer located in the second non-display area;
• the first dummy spacer comprises a first linear pattern with a first uniform width extending in the first direction and a first support pattern disposed directly on the first linear pattern;
• the second dummy spacer comprises a second linear pattern with a second uniform width extending in the second direction;
• the first uniform width of the first linear pattern is different from the second uniform width of the second linear pattern;
• a width of the first support pattern is smaller than a width of the first linear pattern;
• and
• an extension length of the first linear pattern is equal to a length of the first seal pattern in the first direction, and an extension length of the second linear pattern is equal to a length of the second seal pattern in the second direction.
